Who's Winning the Senate Fundraising Battle? — PICTURES

With just one more fundraising quarter to go until the election, time's growing thin for Senate candidates hoping to outpace their opponents.

As reported by Hotline on Call, during the second quarter of the year, Senate Democrats largely out-raised their rivals. Collected here are the latest round of winners and losers —the best- and worst-performing fundraisers — for the upcoming elections.

WINNERS
Republican Sen. Scott Brown's Democratic challenger, Elizabeth Warren, is hands down the cycle's most impressive fundraiser, bringing in $8.6 million this quarter.

WINNERS
In New Mexico, Democratic Rep. Martin Heinrich nearly tripled his first-quarter output, jumping up from $490,000 to $1.4 million during the second quarter and banking $1.8 million. Not to be outdone, former Republican Rep. Heather Wilson topped Heinrich's mark, hauling in $1.6 million and ending the quarter with comparable money ($1.6 million) in the bank.(AP Photo / Craig Fritz / Jake Schoellkopf)
